So… this happened.

During a game of “Will Kathy Know Them?”

The 63-year-old couldn’t properly identify photos ofRyan ReynoldsorJustin Timberlake.

And earlier in the Wednesday episode, she didn’t know whoMelissa Etheridgewas.

Then a photo of Lizzo popped up amid the game.

She was referring toPreciousfilm starGabourey Sidibe, who is most definitely not Lizzo.

Minkoff, 39, tried to smooth over the response.

“She is precious, though.

Lizzo is precious,” she said.

“That’s what I call her!

Her nickname is Precious, to me,” Hilton replied.

On the one hand, Hilton didn’t know virtually any of the celebs.

On the other hand, she got some heat for mistaking the two plus-sized Black women.

TF is this???"

Internet personality Kalen Allen was also among the responses.

Neither Lizzo nor Sidibe have commented on the goof.
